it is important to have 2FA for second security. I prefer to take google auth, but even if you have it, be carefull with everything
These days very important 2 Factor Authentication for our accounts. It will secure our accounts from unauthorized login. Very effective guide. Thank you.
Good guide bro. It's nice to see you helping others. I'm new to cryto and definitely going to implement 2FA into all my exchanges and email accounts.
Yes, I do use 2FA for my online accounts and since there is a possibility of losing the device or damaging it, I also have back up codes to deal with such situation. However, I believe that even 2FA wouldn't help us in case of the data compromisation from the server side and hence I have rarely maintained more than 20% funds online. 2FA really helps to protect the account but changing primary passwords more often should be a regular practice.
Absolutely, there is no way to protect yourself from that other than keeping thw majority of your holdings off the exchanges.

If you are holding big amount of money that you dont want to lose, then yes you must use it. but again learn how to use it and how to recover it if you lose your phone.
That's why you need to backup your phone so you can recover it from backup 
I have this notification in poloniex but I'm not sure whether I need it or not.

The idea behind Two Factor Authentication is:
- you know something: your password
- you have something: the 2FA code generated by your app
Let's say you go to an internet cafe (they still exist right?). You go to a website and you enter your password. Unfortunately the owner of the cafe has a keylogger installed on all the computers and he is tracking the keys that you've typed in. Now he has access to your account.
If you had 2FA on he would have been able to do step 1 (your password), but wouldn't be able to login because he doesn't have your 2FA code.
I would enable it where-ever you can, especially on things like email. Because most sites use your email for password resets.

Two factor Authentication is mostly again online threats and hackers, if youre in situation someone may look at your phone and steal passwords then you should choose people youre hanging with more carefully
LOL it can happen and you can prevent that easily. for example some exchanges give you the option to put 2FA on withdraw or even on sell orders. so he will have to get the code more than once.

Two factor Authentication is useless without a strong password to your phone or carefully keeping your phone out of reach of people who can access your account.
Well if you lose your phone, you have the recovery codes saved one the side, if you are fast enough to get smartphone from someone you can save yourself.
There is always way to get hit, but it does help a lot from online attacks

Why even bother to use Google Authenticator? You can download a open source 2FA app such as andOTP[1] that has the option to backup and restore 2FA codes. Then, you can just set up your 2FA and upload an encrypted backup to any free cloud provider you want. Never losing access to your accounts again.

That is also an option. Never used that so I can't guide someone less

Good guide mate. It's nice to see people helping others off their own back - good on you.
I factory reset my android phone a few months back in a hurry and wrongly assumed my 2FA codes would be backed up to Google and reinstall on the other side. Let's just say I was wrong. Took me up to a month to get access to all my exchanges.
Everyone, take 2FA seriously - back that stuff up!
Good luck.

I have been through this before, I lost my phone and I had no backup codes for the google authenticator. I manage to recover all my accounts back but it took around 2 weeks to get all back. You need to prove that you are the owner of the account.
